The Snyder Industries 4900 Gallon ASTM XLPE Heavy Duty Vertical Storage Tank is a crosslinked-polyethylene vertical storage tank built for large-volume water and heavy-duty liquid duty. It holds 4,900 gallons in a 90-inch diameter, 202-inch tall body on a 90.0 x 90.0 inch footprint, molded in Natural White. The tank carries a 1.9 specific-gravity rating, which is why it earns the "heavy duty" designation - the wall is engineered for dense contents, not just water.
Will it work for your site?
Filled with water, this tank carries roughly 40,866 pounds of contents, and it is rated to hold as much as 77,645 pounds at its full 1.9 specific-gravity ceiling. At 4,900 gallons of water it runs at about 53 percent of that rated ceiling, so it has real density headroom for fluids heavier than water without stepping up to a different tank. This is a tall vertical - 202 inches, about 16.8 feet, to the top - so treat height as a hard install gate: confirm overhead clearance and fill access, and engineer the concrete pad for the loaded weight of what you are actually storing across the 90 x 90 inch footprint, from 40,866 pounds of water up to the rated 77,645. Both numbers matter when you pour. To match gallons to your demand, run the Tank Sizing Calculator and read the Tank Sizing Guide; for the base, our guide on concrete pad sizing for above-ground polyethylene tanks walks the ACI framework.
Fittings and access
The tank comes configured with a flange, an 18-inch PE threaded and vented fitting, a manway with 15-inch access, two 3-inch S.U.M.O. fittings, a 12-inch by 14-inch fitting, and a flat fitting location. The 15-inch manway access lets you inspect and clean the interior after installation. Match your gasket material and bolt pattern to the flange and manway ports before you plumb, and verify the exact fitting sizes and elevations against the technical drawing on this page - inlet, outlet, and vent placement drive your pipe runs.
XLPE versus HDPE - the decision to get right
This is a crosslinked (XLPE) tank, not standard HDPE. Crosslinking builds a denser, more impact-resistant wall, which is what allows the higher 1.9 specific-gravity rating on a vertical tank this size. If you are weighing the two resins for your duty, our guide on Snyder XLPE vs HDPE: when crosslinking matters shows where the difference earns its cost. If this is fire-reserve or rural water storage, the rural fire-water reservoir design guide covers NFPA 22 sizing and cold-climate freeze protection.
This vertical storage tank ships LTL freight from the Snyder plant in Lincoln, Nebraska, quoted live to your ZIP - use the Freight Cost Estimator for a rate, or call 866-418-1777 and we will handle the quote for you. At 40,866 pounds or more of shipped weight, a tank this size moves on a dedicated LTL shipment, so confirm your delivery site has the room and offload equipment to receive it before you order.
